On top of being a gaming paradise, the BYOC can feel like you’re visiting the gaming equivalent of a an auto show — PCs with ridiculous horsepower and monster truck-esque casings. Truly a site to behold.

During last year’s QuakeCon, the Bethesda Underground team talked with contestants competing in Modders-Inc Computer Case Mod Contest. See some of last year’s highlights in the video above.

Interested in competing this year? Modders-Inc is back at it again — with three categories for attendees to compete in:

Case Mod Classic: class consists of any mod that is built from an existing retail or factory PC Case.

Scratch-Build Mod: consists of any mod built from anything other than a PC Case.

id/Bethesda Themed Mod: consists of any mod themed on id Software/Bethesda or any their games.
